Abstract

THE use of anaesthetics in fishery work, mainly in the transport of live-fish and also in handling fish for tagging, fin-clipping, weighing and stripping has been recognised by fishery workers everywhere. In live-fish transport, anaesthetics are useful in lowering the metabolic activity of fish, which facilitates the transport of more fish in a given quantity of water for a longer time. It has also been proved that anaesthetics make the otherwise time consuming work of tagging and fin-clipping much easier and also lower the mortality of the fish due to handling. Considerable effort has gone into a search for a proper anaesthetic and its different concentrations to give varying degrees of anaesthesia useful for works from tagging to transport of live-fish.
